Abbility to Change RATE OF FIRE (betwen 2 rates, 15 and 25 for example) directly by pressing program button

The new version 0.6 now supports Presets which will accomplish this. The new programming allows you to configure 3 complete seperate firing configurations (firing mode, firing rate, and burst size). To toggle through the presets, you press the tactical button when the gun is on. The LED will flash green indicating which preset you are in (one flash for preset #1, two flashes for preset #2, and three flashed for preset #3).

Instructions for configuring the presets are on the wiki:http://code.google.com/p/phenomx7-etrigger/wiki/Home

Thanks so much man. Give me some time to try this! . I need to buy the programer first. Your work is great!

Hello! I am very impressed by your work here and have ordered some cheap programmer to attempt some of this myself.

My programming skills are sub-par and I may not be as able as willing to contribute, though, fair warning. I wondered about two things primarily, to start things out. One, is it reasonable to buy a new chip and experiment with that one, using your code as the starting point? By doing this I will keep a spare chip and sleep at night Two, I also have an X7 classic I'd like to experiment with, how much of the code would conceivably need to be rewritten to suit the classic's trigger system and solenoid?

I do not have any experience with the x7 classic. I would not recommend using this software on the x7 classic eGrip. I'm not sure if it uses the same chip as the Phenom, so the programming here may be useless. If you can, please take a picture of the board (as detailed as possible - all sides of the board) and we might be able to figure out if it will work. Is your board from Tippmann, APE, or another manufacturer?

If it does use the same chip, you can buy new chips to test with at several vendors (digikey, mouser, ...).

This is the chip that goes in the Phenom:http://www.digikey.com/product-detail/en/ATTINY44A-SSU/ATTINY44A-SSU-ND/1914708

Since the chip is rather small and difficult to test with, you can get the same chip in DIP format to fit in a standard breadboard (warning: this chip is only for testing the programming, this chip will not fit in the marker):http://www.digikey.com/product-detail/en/ATTINY44A-PU/ATTINY44A-PU-ND/1914707

So I disassembled the eGrip on my X7 classic. Under a sticker on the chip I found the markings of an Atmel ATtiny44. (jackpot!) It is a stock Tippmann board, and from what I can understand the board is very closely related to the Phenom, moreso than the 98c and A5. I also own a 98pro and will disassemble it tomorrow to see if it is the same chip. This project may help a bunch of people if this is correct, not just Phenom users.

I don't have an adequate camera on hand. However, I compared with pictures found online and this is the exact same board, only mine is blue and with the solenoid still soldered on (mine fell off and I had to stick it back on) and a capacitor on the back that reads 6800µF / 10V.

The adapter cradle for the tiny chips looks handy!!! I like that, good find!

I'm not an electronics genius (yet lol) nor do I pretend to be, but just on initial thought I'm thinking that that A5 and 98c boards are going to be completely different and this software may need tons of revamping to make it work. The main thing that tips me off to that is the fact of how each of them turn on. This may be minor, but it does signify in my mind a bit of different circuitry (hall effect vs push button).

Like I said though, this is just theory and though. I'm looking forward to finding out though.

Yes, I may be overreaching in respect to my skill level there. The 98 pro / A5 board is not nearly similar to the x7 / Phenom family. I disassembled it and recognized absolutely zero major components. I'll shelf the idea.

The adapter cradle (I don't know if it's called that but it sounded right) is perhaps the laziest way to reprogram the chips; then again, I am lazy and my rate of success hinges solely on a trial-and-error basis. Plus, I'm a lumberjack by trade and my abrasive, clumsy hands are not meant for precision soldering. Perhaps, with some luck - and a stanley knife - a cradle component like the one on top of that adapter can be soldered onto the motherboard itself. Could be useful for swapping chips fast.

As for the programming itself; from studying pictures and specification write-ups of the two boards, it seems this software is compatible without major modifications. The hardest challenge would presumably be swapping the mechanical mode on the Phenom eGrip with a semi-auto mode (or another slot for programmable firing modes, like on the APE board). Without modifications, I presume the board will either default to the programmed setting, not function on semi-auto, or not function at all. Murphy's Law tells me it's the latter, so I'll begin scouring the code itself to look for the loops I need to focus on. The two boards may be one magnetic sensor component off from being the exact same board, however.

I am a complete noob at this so bear with me if something I say makes absolutely no sense.

I agree. My neighbor has an eGrip for the A5 and it didn't seem to be powered by a Atmel chip. I wasn't able to get too close, but I would guess by the switches used to modify the firing modes, that it is not powered by a microcontroller.

In the Phenom board, there are three electromagnetic relays that are used to turn on the board, and sense when the trigger is pulled. I may have been wrong in how I'm using them (it has been a burning question in my head since I started). Out of the 3 relays, I'm utilizing 1 of them. 2 of the relays appear to be identical; they sense when the trigger is pulled. The other relay does not appear to connect directly to the micro controller (it is used to power the board).

On the Phenom, there is a rare earth magnet in the safety switch. When the switch is rotated to full auto, the magnet activates a relay to power on the board. I'm not sure how an APE board is powered on for the x7. It's possible that their board has another relay to sense the mechanical safety-switch position as well as full auto. In other words, this may not be possible for the x7 or Phenom without modifying the hardware on the board.

I'll take another look at the relays on my board to see if one of the relays could be used to sense the mechanical safety-switch position.

As for modifying the software, it all depends on the pin-outs of the board:Pins 5 and 7 connect to the relays for the trigger. (their voltage goes LOW when the trigger is pulled). I'm only using pin 5 to sense for trigger pulls. Hopefully this matches the x7 classic. As far as I could tell, there is no pin to control the relay that powers on the board. It's probably connected directly to the voltage regulator to supply power to the chip.

I agree. My neighbor has an eGrip for the A5 and it didn't seem to be powered by a Atmel chip. I wasn't able to get too close, but I would guess by the switches used to modify the firing modes, that it is not powered by a microcontroller.

It is an 8-pin something something that I'm not too familiar with. It'll be a project for a time when resources are scarce I suppose.

There are three electromagnetic relays on the X7C board. Two are on adjacent opposite positions on both sides of where the trigger magnet is situated on a trigger pull, while one is situated on the other side of the board, outside where the magnet in the safety switch "wing" positions itself if you flip it one more step into the programmed mode (for the Phenom, where the electronics kick in). I'm fairly confident, after bending the two mirrored relays a bit back and forth, that they are essentially giving the same information to the controller. Perhaps there is two of them because of redundancy, or polarity sensing limitations. The safety switch relay is only on one side for obvious reasons. Do you have any insight into the mechanical mode and how it is relayed?

Edit: Well now I feel stupid. Of course the mechanical mode is not relayed, that's the entire point.

I'm wondering if the two sensors are for when the gun is in response mode. To me it makes sense; pull the trigger and one/both get flipped, but while the trigger is in ge pulled position, even if for just that brief second it then senses when the second one gets flipped on th way out to trigger the solenoid?
